hi,
I have successfully compiled openLDAP-1.2 on unix svr4(NCR MP-RAS). The LDAP
server used in our organization is Netscape directory server ver 3.1.
Using ldapsearch I am able to query the details from the server. But when I try
to modify my details on the server with ldapmodify, I get the error message as
follows:
$ldapmodify -h 192.168.200.172 -p 389 < raju.ldif
modifying entry uid=rajukv,ou=Koramangala2,ou=Bangalore,ou=India,o=Wipro
ldap_modify: Can't contact LDAP server
ldap_modify: additional info: Referral:
ldap://oxygen.wipro.com:389
The file raju.ldif is the output of ldap search with some entries modified.
I have compiled openLDAP without any of the servers(slapd, slurpd,ldapd etc) as
I require only the clients. Can you tell me what is wrong?
Thanks,
Raju
